Genetic damage of operating and recovery room personnel occupationally exposed to waste anaesthetic gases
2019
Occupational exposure to the waste anaesthetic gases (WAGs) is a crucial problem for healthcare personnel. Cancer is among the potential long-term adverse effects of WAGs. The present occupational molecular epidemiology study was conducted in healthcare personnel (anaesthetists, nurses and technicians; n = 46), working in operating rooms (ORs; n = 34) and recovery units (RUs; n = 12) of the same hospital, to assess the genotoxicity risk of WAGs exposure. Twenty-one healthy available hospital staff allocated to other wards, without the history of working in ORs and RUs were the control group. A micronucleus test was carried out for peripheral blood lymphocytes (PBLs) and buccal epithelial cells (BECs). Exposure to the anaesthetics was assessed with sevoflurane concentrations and inorganic fluoride levels in post-shift urine samples of the healthcare staff. As an exposure marker, sevoflurane concentrations in ORs and RUs were measured using passive samplers. The micronuclei frequencies were increased in bot...
